Abstract: Objective To evaluate the effect of ureteroscopic treatment for upper urinary tract obstruction. Methods A total of 56 cases of upper urinary tract obstruction were treated under ureteroscope by using direct-vision dilatation, electrocauterization or balloon dilatation. Results A successful dilatation was achieved in 49 cases (87.5%, 49/56) whereas a failure was encountered in 7 cases. There were no complications such as ureteral perforation, rapture or heavy bleeding. A follow-up for 0.5~3 years (mean, 2.5 years) in 43 cases was carried out. The obstruction disappeared in 33 cases, remained in 6 cases, and relapsed in 4. The hydronephrosis disappeared in 30 cases, subsided in 5 cases, and had no changes in 8. Conclusions The treatment of the upper urinary tract obstruction under ureteroscope offers advantages of minimal trauma and satisfactory outcomes.
